1. When youâ€™re using TurboCADâ€™s backgrounds with a floor-like plane which should receive a shadow for your added subject to render your scene more realistically, Iâ€™m thinking of a house or even a telescope sitting there casting its shadow on the ground. Has anyone done that already?

2. If using a loft normally youâ€™ll get s straight leap (transition) from one 2D shape to another 2D shape, but if you need a conformed path for the loft the option is given. On several occasions this last feature doesnâ€™t ever work for me. Am I forgetting to do something do you suppose enabling this modification?

Yup. That's what the "Shadow catcher" Reflectance is for. Create an object (such as a large thin 3D Box) to receive the shadow and create a new Material for it, using "Shadow catcher" Reflectance. Click the green "question mark" icon in the Material Editor to learn how to use it.

If you use three or more profiles for the loft, the transition from one to the next will be a smooth curve, even without guide lines.

Lofting with "Guide lines" is tricky and unreliable. It works for me only if all profiles are essentially identical (all having the same number of vertices); if the guide lines are 3D Splines; and if each guide line touches the corresponding vertex on each successive profile -- and it still might not work.
